;ROADWAY WITH nvrrnovnn CURBSTONE AND. e-u'r'rnni Application filed July 12, 1928. semi No. 292,169.

This invention relates to roadways, and

particularly to curbstone and gutter portions of roadways. Heretofore, roadways have been frequently built with curbstones to separate the soil from the road, and often gutters have been built adjacent to the curbstone ant between it and the roadway proper for bettering the drainage of the highway. These curbstones and gutters were preferably made outof concrete, cement, or'similar forming and hardening materials, which were poured in place directly at the roadway, the method necessitating first forming the curbstone at the road and permitting it to set, then forming the gutterway adjacent to the curbstone and permitting it to set, and finally completing the roadway between the opposite gutters after) they have thus set, all of which consumed of the same run .of material and in the same operation the unit comprising the curbstone section and concomitant'section of gutter.

Other objects and advantages will here-- inafter appear.

In the accompanying drawings,

-Fig. 1 is a perspective view of the curb stone section and concomitant gutter section, constituting the article of manufacture of thisinvention.

Fig. 2 is a cross section and perspective view of the improved roadway, and shows the fabricated curbstone and gutter units of this invention, as they appear 'when laid in the roadway. v

I The article or block of the invention, comprises a thick horizontal member 1 of elongated polygonal formation in plan, and a thick vertical member 2 formed integrally with an ,extending transversely of and upwardly from the inner end portion of the horizontal member. The member 2 and the underlying or inner end portion of the horizontal member 1 constitute the curb portion ing of the gutter.

tal member 1, which is located outwardly be yond the curb portion, contitutes the gutter portion of the block.- The curb portion 2 gradually increases in thickness outwardly ion 3 to said portion so as to reinforce the portionsv at'their point of juncture. This thickened portion 4 of the curb portion 2 is concave to effect a better drainage and clean In manufacturing this of the blocln and that part of the horiaonfrom a point slightly above the, utter porarticle a mold is prepared which may be utilized with any suitable molding machine for casting the article out. of one run of material in a single molding operation, after which the article may be baked in any suitable manner. Any suitable cementitious material which will serve the desired purpose maly be utilized for they making of this artic e. I

I After the articles 1 have been manufac-. tured they may be put into the roadway 5 in the manner shown in Fig. 2, to thus constitute the-completed curbstone 6 and gutter 7 of the'roadway."

The articles or blocks are of elongated polygonal formation in plan, and are arranged with their longitudinal axes at right angles to the axis of the roadway As the gutter portions are thick and extend trans-- versely of-the roadway, such portions will not crack, break of crush under the weight of any vehicle passing thereover or resting thereon. Furthermore, this formation of the blockspermits them to be laid in a comparatively short time and with comparatively little labor and expense. As the curb portions of the blocks are thick and due to their increased thickness abo'veand below their line of juncture with the gutter portions, the curb portions. will not crush,

.crack or breakv under any strain to, which they may be subjected as the result of a vehicle. backing against them or passing over them.' The blocks are comparatively narrow, durable, strong and practically indestructiblef As the articles 1 are. made sufficiently narrow they may be readily laid to follow any curvature, bend, or curved grade of the roadway 5 Due to the articles 1 being fabricated at the manufacturing plant with I proper machinery, available processes, and desirable materials, the produced curbstone and gutter of this roadway is superior to those built heretofore by pouring material directly into the roadway, and

as the articles 1 can be put in place conveniently and rapidly it results in an economical, well appearing, strong, durable, efficient, and improved curbstone and gutter for the roadway.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I

. plan and adapted to be laid with its longitudinal axis angularly of the axis of the roadway, and a thick vertical member formed integrally with and extending transversely 0i and upwardly from the inner end portion of the horizontal member, and the vertical. member increasing outwardly in thickness from a point slightly above the horizontal member to said member so as to reinforce the members along their line of juncture.

Signed at New York, in the county of New York and State of New York, this 11th day of July, A. D. 1928.
